The truck hit an embankment, went through the median, struck a bridge and burst into flames. 58 year old driver Glen Boyer was able to escape. He was flown to a hospital in LaCrosse, Wisconsin with a shoulder injury.

Investigators at the scene said they believe the driver either fell asleep or was tired. No one else was hurt.

Westbound traffic was closed for a time to clear the mess. The truck was carrying cheese.
